The bright blue swirls in the upper left part of this image are part of a phytoplankton bloom that has been flourishing in the Barents Sea for over a month.

The bloom was initially observed by Norway, between the country’s northern coastline and the Svalbard Archipelago. It has since spread eastward and can now be seen near the Norway-Russia border, north of Russia’s Kola Peninsula and northwest of Kanin Peninsula (framed by sediments, right).
